Heidi LeHew felt funny eavesdropping and observing, but she couldn't take her eyes off the six women in the row in front of her at the Kenny Chesney concert Saturday at Miller Park.

They were dancing, swapping cowboy hats, high-fiving, snapping tons of photos and just having a ball.

Heidi, who lives in Madison, was enjoying the show with her husband, Aaron. The kids were at home with grandma.

One woman in particular caught Heidi's attention.

"She was beautiful. She was petite with a short pixie haircut that only some girls can pull off. I noticed her because of her smile. It never left her face," Heidi would later write in a long Facebook post.

In that same essay, Heidi goes on to say she was forever changed by what she witnessed that day. You go to a concert or any event expecting one kind of experience, and sometimes you come away with a profoundly altered appreciation for life.

As the sky darkened and the evening air cooled, Heidi saw that the woman was losing strength. Her friends held her hand and embraced her. One of the woman's friends turned to Heidi and surprised her by saying she had never been to a country music show before.

"We're here celebrating our friend," the woman told Heidi, who assumed she perhaps meant it was her birthday.

The friend spoke again. "She has stage four breast cancer," she said. "This concert is on her bucket list."

You hear about people who find out they may not be lucky enough to grow old. Some of them grab for as many life experiences as they can get. They think of things they must do before they, as the expression goes, kick the bucket.

"I had never met anyone with a bucket list before," Heidi wrote, particularly someone who appeared to be close to her young age, 32.

"My heart sunk, and right then time literally stood still. How could this be? She was so beautiful, the life of the party. Full of life but losing it all right before our eyes."

The woman turned to Heidi. In the midst of some 40,000 people at the show, their eyes locked. "She knew that I knew now," she wrote.

Heidi was crying as she put her hands on the woman's face. She said she was beautiful. She said she was the one who had sparkled so effortlessly tonight. The two strangers embraced.

Chesney was still singing when the woman and her five friends headed for the exit. A long day of sun, drinks and music — on top of the effects of cancer and the harsh drugs used to fight it — and this bucket-lister was spent.

Heidi sat down on Sunday and wrote about the extraordinary encounter. She posted it on Facebook, thinking that would be the end of it. She did not even know the name of the woman she had met.

But, Wisconsin being the small world that it is, two friends of Heidi knew this woman and her friends. They recognized that Heidi was writing about a woman named Molly Fuglestad.

By Tuesday, Heidi and Molly were linked up and chatting on Facebook. The piece that Heidi wrote quickly spread across social media.

Heidi at first was worried how Molly would react to her description of their meeting. But Molly and her friends were touched by how perceptively Heidi had captured what she witnessed at the ballpark.

I reached Molly by phone. She lives in Jefferson. She and her husband, Darin, have three children — 6-year-old twins Michael and Mason, and a daughter, Annalyse, 4. Molly is 36 and works part time as a speech therapist.

In 2010, she was diagnosed with breast cancer. She thought she was in the clear after a double mastectomy, chemotherapy and radiation, but in 2012, the cancer metastasized in her sternum and spine. She continues to fight it with a cocktail of five drugs injected into her body every three weeks.

She has an abundance of friends and family who give her strength and support and joy. She calls them her army. Some of those troops were dancing alongside of her at the Chesney concert.

Molly has other stuff on her bucket list. Last week, she went to an all-women event at a firing range and learned to shoot a pistol. A couple months ago, she joined her extended family on a skiing trip to Colorado.

Her cancer is treatable but incurable.

"I think with a diagnosis of stage four, you appreciate life so much more. It makes you want to live your life as if it's your last day," she said.

Heidi plans to send her Facebook post to Kenny Chesney. And she is joining Molly's army.

"It's just crazy how all this worked out," Molly said. "I asked Heidi, 'Are you religious? This is a God thing at work, that our worlds collided like this.'"
